MADDRA J. HEWLETT, OF PADUOAH, KENTUCKY, ASSIGNOR OF ONE-THIRD TO JAMESOWEN, OF SAME PLACE.

TYPE-WRITING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 439,068, dated October21, 1890. Application filed May 17, 1390. Serial No. 352,155. (Nomodel.)

To all whom it may concern:

Be it known that I, MADDRA J. HEWLETT, a citizen of the United States,residing at Paducah, in the county of McOracken and State of Kentucky,have invented certain new and useful Improvements in the Type-'NVritingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has relation to type-writers, and the object sought to beaccomplished is to produce a machine more readily adapted for use inwriting upon books, pamphlets, postal-cards, envelopes, &c., and uponany width paper than the devices heretofore in use.

With these ends in View my invention consists in certain peculiaritiesof construction and combinations of parts more fully de scribedhereinafter, and pointed out in the claims.

Referring to the accompanying; drawings, Figure 1 is a front perspectiveof my com plete arrangement; Fig. 2, a rear elevation; Fig. 3, a sideview of the operating portion of the machine, showing the printing-leverdepressed and the type-segment thrown up to its farthest extent; Fig.4,a front view through line a; m of Fig. 3, and Fig. 5 a detail of theinking-pad.

I provide a plate 2 of suitable metal, on which the book-leaf or othermatter to be printed upon is placed, and this plate is provided at itsopposite ends with buttons 3. A rectangular metallic frame 4 fits downupon the plate 2 and has elongated slots 5 in its 0pposite end bars,through which the buttons 3 project and are then turned to clamp theplate and frame together, and hence the leaf between them. The side barsof the. frame 4 are turned up and doubled overto form flanges 6,extending its entire length and leaving between them and the side barsgrooves or ways 7. A transverse frame 8 extends across between theflanges 6, being provided at each end with an upright standard 9, thebases of which are turned at right angles to form projections or feet10, fitting and traveling in the grooves or ways 7, and a rock-shaft 11runs through said frame and has bearings in the standards 9. This shaftprojects through said standards and out over the flanges 6, and isprovided with cams 12 on each end, arranged to bear upon said flanges, asuitable handle or crank-arm 13 also being formed at one end of theshaft, by means of which it is turned. It will be seen that by turningthe arm 13, and hence the shaft, the cams 12 will bind upon the flanges6 and tightly clamp the latter between them and the projections 10 ofthe standards 9, thus holding the frame 8 stationary at any pointdesired. The flanges will have divisionmarks 14, so that the frame canbe accurately adjusted. The feed-bar 15 projects from the opposite endsof the frame 8 and is bent out from the same at each end, as at 16, toallow printing the full width of the plate 2, and the upper straightportion of the bar is provided with the usual teeth 17.

The main standard of the traveling portion of the machine has a base 18,from which extends a substantially semicircular upright 19, having threeseparate arms 20, 21, and 22 extending up behind the feed-bar and eacharranged to straddle the same at their upper ends and held thereto bytransverse pins 23, thus forming sliding guides or bearings travelingfreely on the feed-bar, extending through the arms 20 and 22 and beneathsaid feedbar. The arms 21 and 22 inclose one tooth of the feed-barbetween them and are provided with beveled adjacent faces 24 25, for apurpose hereinafter explained.

The printing-lever 26 is arranged at its inner end 27 to straddle thefeed-bar, and it is pivoted on ears 28, projecting from the stand ard 19on either side of said feed-bar. A gravity feed-dog 29 is pivotallyconnected to the lever 26, and is adapted to engage the tooth of thefeed-bar between the arms 21 and 22.

The opposite vertical portion 30 of the main standard has formed at itsupper end a horizontal platform 31, from which is erected the post 32,having an outwardly-extending upper end 33, connected to the centero'fthe index-plate 34, which is semicircular and has a flaring annularsurface 35, on which are placed the usual letters and figures. Beneaththis index-plate is situated the type-carrying segment 36, consisting ofthe circular portion or bearing-plate 37, pivotally secured to thestandard 30 by a stud 38, and a semicircular flange 39. A slot 40 ismade in the center of this flange and extends almost its entire length,and the type-band 41 is stretched over the lower face of the flange withthe raised line of type 42 directly over the slot 40. Clasps 43 areprovided at each end,which are arranged to removably clamp the typebandto the flange by straddling the latter and inclosin g the ends of theband, thus making the substitution of new type an easy matter.

An indicator or arm 58 is secured to the upper portion of the plate 37and is ,bent out and thence back over the face of the indexplate andprovided with a finger-piece 59, so that by means of this arm thetype-segment can be shifted-to any point desired.

The punching-bar 44 is arranged behind the post 32 and has a squareupper end 45, operatingin a corresponding opening in the platform 31, toprevent it from turning, and its lower end extends through the base 18,directly over the slot 40. This punching-bar has a rearward projectionor offset 46, projecting beneath the printing-lever 26, from the centerof which extends downwardly a rod 47, passing through the base 18 andprojecting slightly beyond the lower end of the bar 44. A coil-springsurrounds the punching-bar between the projection 46 and the base 18 andacts to keep the bar in elevated position. The inner edge or rim of theflange 39 has a series of notches 48, one for each type, and the rod 47is adapted to engage said notches, as will hereinafter appear.

Beneath the flange 39 and the type an inking device is situated, whichconsists of a frame 50, having rearwardly-extending arms 49, surroundingthe shaft 11 and sliding on it, and an upwardly-turned lip 51, engagingframe 8 to hold the inking device in proper position. The centralportion of the frame 50 is provided with a longitudinal slot 52,arranged to come beneath the lower end of the punching-bar, and a lip 53 is turned up from said central portion to bear against the front faceof the type-segment to further steady the inking-frame. On either sideof the inking portion arms 54 project, and on them are placed theinking-pads 55. The inking-frame is moved along with the type-segmentand connections by means of lugs 56, projecting upwardly from it andengaged by corresponding lugs 57, depending from the base 18 of the mainstandard. Thus it will be seen that whichever way the carriage is movedthe inking-pad is carried with it, and at the same time access can bereadily had for purposes of reinking or renewing. the pads by simplythrowing back the type-segment and connections.

The preferred construction of my device having been set forth, I willnow proceed to describe its operation. The book-leaf or other.

matter to be printed upon having been clamped between the plate 2 andframe 4, as previously set forth, and the feed-bar having been set atthe desired line, by turning the rock-shaft 11, and thus binding thecams 12 upon the flanges 6, the operator will slide the carriage to thepoint at which it is desired to commence. The letters and figures on theindex-plate accord with those upon the typeband, and consequently whenthe indicating arm 58 is brought over the letter desired the same letteron the type-band will be directly beneath the punching-bar. Now upondepressing the lever 26 it will be seen that the feed-dog 29 will act toshove along the carriage one notch, and at the same time it will bearupon the projection 46 and push down upon the punching-bar and rod 47.Said punching-bar being, as previously stated, directly over the slot inthe type-flange will be pushed through the latter and upon the type,which has been brought directly beneath it. At the same time the rod 47engages the notch opposite the letter being printed, and thus holds thetype-segment stationary and a clear imprint is obtained. The rod 47,extending slightly below the punching-bar, limits the movement of thelatter by coming in contact with the plate 2. When the printing-lever isreleased, the reaction of the spring 60 will return the punching-bar,rod, and lever to their normal positions ready to be again operated toprint the next letter desired. In the normal position of these parts thefeed-dog will be resting against the beveled edge of the arm 21, andwhen the le-.

ver is depressed will be guided down said inclined surface into thetooth, and when the carriage has been carried the length of this tooththis dog will strike the beveled edge of the beveled arm 22 and belifted free of'the rack while the punching-bar is operating to print theletter. WVhile one letter is being printed those on either side of itwill be pressing upon the inking-pads 55, and .thus the type will bekept constantly inked. The spacing is accomplished either by ahalfstroke of the printing-lever or by bringing the indicator-arm to avertical position when a blank is left in the type-band.

It is evident that my arrangement could be varied in many slight wayswhich might suggest themselves to a skilled mechanic. Hence.

I do not wish to limit myself to the precise construction herein shown,but consider myself entitled to all such slight variations as comewithin the spirit and scope of my in- Vention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is V 1.
